困难 级别的解题技巧
| 技巧 | 描述 | 级别 |
|---|---|---|
| Diagonal Enumeration | For each clue, enumerate all combinations of N digits (allowing repeats, 1–9) that sum to the clue value. | 初级 |
| Repeating Digits Allowed | Unlike Killer cages, Little Killer diagonals can repeat digits as long as standard row/column/box uniqueness is preserved. | 初级 |
| Short Diagonal Logic | A 1-cell diagonal directly gives that cell's digit. A 2-cell diagonal with clue C has limited pairs — enumerate them immediately. | 中级 |
| Cross-Diagonal Intersection | When two diagonals share a cell, the shared cell must satisfy both sum constraints simultaneously. | 高级 |
| Row/Column Interaction | A diagonal cell belongs to a row, column, and box — combine Little Killer sum constraints with standard uniqueness rules. | 中级 |

在困难需要掌握的技巧
- Hidden Pairs technique — Where two clue diagonals cross, the shared cell must satisfy both sums — the arithmetic squeezes neighbouring cells until pairs hide in the corners of crossed boxes.
- X翼技巧 — Long diagonal sums near the minimum flood the diagonal with small digits, pushing 8 and 9 into few legal cells per row — hard Little Killer fish swim on the high digits.

杀手数独
The cage version of the same idea: sum clues with a no-repeat rule that makes the arithmetic tighter than on diagonals.
三明治数独
Also driven entirely by numbers written outside the grid — sums between the 1 and 9 instead of along diagonals.
摩天楼数独
Another outside-clue variant, replacing diagonal sums with visibility counts read from the grid's edges.
